Answer: B. -6,5,4

Step-by-step explanation:

To find the coeffiecient in

-6x +5y + 4x + 9

we will first have to know what coefficients are.

Coefficients are constant quantitiy placed before a variable, this contant quantity must be placed in such a way that it is multiplying the variable.

So, from the above definition; we can deduct that -6 is placed before the variable x and it is multiplying x.

-6 is a coefficient of x.

5 is placed before the variable y and is multiplying y, then 5 is a coefficient of y.

4 is placed before the variable x and is multiplying x, then 4 is a co-efficient of x

But 9 is not attached to any variable, so 9 cannot be called a coefficient but rather 9 is just a CONSTANT.

Therefore the coefficients are; -6, 5 and 4

Solve for x.<br> 144°<br> 18 degrees<br> 30 degrees<br> 48 degrees<br> 120 degrees
disa [49]

Answer:

<h2><u><em>x = 18 °</em></u></h2>

Step-by-step explanation:

you have a rotation angle of 360 °, take out the known values ​​(360 ° -90 ° -144 ° = 126), 144 ° is part of a flat angle of 180 °, from 180 ° remove 144 and you have 36 °, they are opposite angles therefore the same. therefore 360 ​​- 144 - 90 - 36 - 36 = 54.

54 is 3x, so x = 18 ° (54 : 3 = 18)

\frac{35}{4} feet below the surface

adding the 2 quantities

3 \frac{1}{2} + 5 \frac{1}{4}

= (3 + 5 ) + (\frac{1}{2} + \frac{1}{4})

= 8 + (\frac{2}{4} + \frac{1}{4})

= 8 + \frac{3}{4} = 8 \frac{3}{4} = \frac{35}{4}

X+2y=3 <br> 3y+5y=7 <br> I dont know
Lena [83]

Answer:

Step-by-step explanation:

3y+5y=8y

8y=7(divide 8 in both sides to get y)

y=7/8

x+2y=3...but we already know the value of y, so substitute 7/8 to y

x+2(7/8)=3

x+14/8=3

x=3-14/8

=1.25
